A Practical Primer On Motor Drives (Part 5): Three-Phase AC Line Current And Winding Configurations

Focus:

In the previous part, the measurement of single-phase ac currents was described. This broad overview on motor drives continues here with a description of the current vectors in three-phase ac systems, how current flows in wye and delta winding configurations, and how it is measured.

What you’ll learn:

• How to understand wye and delta three-phase winding conventions
• How to measure three-phase ac currents using oscilloscopes
